ABSTRACT
Objective:To explore the interleukin-31 protein expression in the hypertrophic scar of incision tissue after surgery and its underlying pathological impact.Methods:From February 2022 to February 2023, three HS patients scar tissue (HS) and their normal skin tissue (Control, NS) were obtained. Two patients were female and one patient was male. The tissues were fixed in 4% formalin and embedded in paraffin. Haematoxylin-eosin (HE) stain and immunohistochemical stain were used to evaluate the epidermal thickness, myofibroblasts of dermis and the expression level of IL-31 between HS and NS.Results:The epidermis thickness was (303.88±46.03) μm in HS group, while (133.02±17.40) μm in NS group ( t=12.60, P<0.001). The expression level of IL-31 protein was measured by IRS score and positive cell density. The IRS score was 9.89±2.03 of the basal layer in HS group and was 4.33±1.66 of the basal layer in NS group. The positive cell density was 786 343.83±159 627.97 of the basal layer in HS group ( P<0.001) and was 555 457.61±128 097.21 of the basal layer in NS group ( P=0.014). In the dermis layer, the IRS score was 7.11±1.05 in HS group and was 4.33±0.71 in NS group, the positive cell density was 156 760.97±26 046.10 in HS group ( P<0.001) and was 49 576.01±52 369.33 in NS group ( P<0.001). In the dermis layer, the count of myofibroblasts was 120.44±15.75 in HS group while was 27.39±14.89 in NS group ( t=23.79, P<0.001). Conclusions:Our study demonstrates that both myofibroblast count and IL-31 protein expression level are notably increased in HS patients. The expression of IL-31 protein is prominent in the cytoplasm of myofibroblasts, basal cells, macrophages and mast cells which could implicate that IL-31 may be a potential therapeutic target to enhance the resolution of HS.
ABSTRACT
Objective:To compare the anti-androgenic effect of cyproterone acetate (CPA) and spironolactone (SPL) on male-to-female transsexuals.Methods:From January 2012 to September 2021, 185 male-to-female transsexuals (95 using CPA and 90 using SPL) who visited the Peking University Third Hospital and under stable medication for ≥3 months were enrolled, aged 16 to 40 (23±5) years. General information and laboratory indicators of the last visit were collected for a cross-sectional study.Results:The median doses of antiandrogens in the CPA group and SPL group were 25 mg/d and 80 mg/d, respectively. And the median dose of oral estradiol valerate in both groups was 2 mg/d. Testosterone level in the CPA group was significantly lower than the SPL group [0.7 (0.7-1.5) nmol/L vs. 13.2(6.7-18.4) nmol/L, U= 6 970.500, P<0.001]. The CPA group also had better subjective effects on testicular atrophy, erection decrease, body hair decrease, skin softening and figure feminization (all P<0.05). The prolactin level of CPA group was significantly higher than that of SPL group [21.5 (12.6-30.1) ng/ml vs. 11.9 (7.7-20.0) ng/ml, U= 2 053.500, P<0.001]. Conclusions:CPA has a more significant effect on lowering testosterone levels than SPL, and is better than SPL in terms of testicular atrophy, erection decrease, body hair decrease, skin softening and figure feminization, albeit with a potentially higher risk of hyperprolactinemia.
